The parts label is respectively in the accompanying drawing: wheel, the interior wheel of 7-, 8-outboard wheels, 9-support, 10-jointed shaft, 11-piston rod, 12-cushion pad, 13-increase piece, 14-guide pass, 15-track base, 16-rollgang, 17-motor, 18-gearbox, 19-reel, 20-steel wire rope, 21-pulley, 22-magnetic induction near switch, 23-cutting mechanism, 24-air inlet/outlet under 1-guide rail, 2-dolly, 3-lift cylinders, 4-magnechuck, the last wheel of 5-, the 6-.

The specific embodiment

Consult Fig. 1,2.Fig. 2 is the A-A cutaway view of Fig. 1 simultaneously.As shown in the figure, guide rail 1 is laid on circle shear rollgang 16 next doors by track base 15, and on guide rail 1, lift cylinders 3 is placed on the dolly 2 dolly 2 by wheel sliding, magnechuck 4 is placed on the piston rod 11 of lift cylinders 3, the steel plate plate face on the corresponding roller-way of card.Motor 17 in the travel driving unit is in transmission connection by gearbox 18 and reel 19, the steel wire rope on the reel 19, and the one end directly is connected with dolly 2, other end pile warp pulley 21 is connected with the dolly other end.Rolled plate enters approach table 16 earlier through laser scribing magnetic force centering, make dual-side to fixation side tangent line G, the side amount of cutting of mobile side tangent line Y is kept in balance, dolly 2 drives lower edge guide rail 1 at motor 17 and advances to steel plate afterbody appropriate location then, piston rod in the lift cylinders 3 is being with magnechuck 4 to descend under the gravity effect, magnechuck gets when descending, the steel plate on the rollgang is pushed down in suction, afterwards, dolly 2 is advanced with rollgang 16 synchronous same-speeds, with the steel plate force feed to the shear blade of right-hand member cutting mechanism 23, shear blade is bitten steel plate, dolly in the magnetic induction of cutting corresponding guide rail 1 front end in preceding appropriate location near switch 22, magnechuck 4 outages, the reversal valve commutation of lift cylinders 3, piston rod 11 rises under gas pressure, the card of magnechuck 4 breaks away from steel plate plate face, motor 17 drives reel 19 counter-rotatings, dolly 2 returns, according to the steel plate length difference, can manually stop dolly, the magnetic induction that also can turn back to the guide rail rear end stops during near switch 22 automatically, finishes a force feed process and begins next block plate of force feed simultaneously, enters the reciprocation cycle of going round and beginning again.Motor 17 is a variable-frequency motor, dolly 2 and rollgang 16 synchronously, with the speed operation, wait with the same speed running of shear blade and to realize by frequency conversion system.

Consult Fig. 1.Because guide rail 1 is positioned at rollgang 16 sides, so dolly 2 should adopt the cantilever structure.The cantilever root slides against cross section on the guide rail 1 of " worker " font by upper and lower, inside and

outside wheel

5,6,7,8, and projecting end then is used to settle lift cylinders 3 and electromagnetism from sucker 4, can guarantee that like this cantilever design dolly steadily walks along guide rail reliably.

Still consult Fig. 1.Piston rod 11 adopts the movable connection method that passes through jointed shaft 3 with being connected of magnechuck 4, make magnechuck 4 when pressing the suction steel plate, can do the accommodation swing for the center by jointed shaft 3, to guarantee that card contacts with large tracts of land face between the steel plate plate face, inhales card securely and pushes down steel plate.

Consult Fig. 2.Lift cylinders 3 can adopt air feed pneumatic linear actuator easily, and cylinder body is upper and lower an air inlet/outlet, and pressed gas is during by cylinder below air inlet/outlet 24 air feed, and piston rod and magnechuck 4 rise, and piston rod descends under the gravity effect automatically when dying.Only need be provided with on the defeated gas exhaust piping of air inlet/outlet 24 can once simple bi-bit bi-pass electromagnetic switch.

Still consult Fig. 2.Cushion pad 12 between magnechuck 4 and support 9 bottom surfaces can be rubber blanket or hardwood.Set up on " worker " font entablature and increase piece 13, guide pass 14 is inlayed to be fixed on by dormant bolt and is increased on the piece 13, entablature upper rail face 14 is fitted with upper and lower, inside and outside wheel respectively, guide pass is a machined surface, the depth of parallelism and flatness requirement are arranged, and can adopt surface hardening to handle, improve hardness and wearability.

Still consult Fig. 2 and Fig. 3.Upper and lower, inside and outside each 2 wheel are placed on separately the wheel seat by rolling bearing respectively, and 8 wheel reasonable Arrangement guarantee that in dolly car body bottom carriage walking is steady, keep linearity and with the shear line depth of parallelism.

The utility model is changed synchronously for the speed of travel that realizes the force feed device and shear rate and roller-way transporting velocity, in the control, used Siemens S7-300 PLC to control the operation of this device, and used Siemens's frequency converter, the change of 5 grades of speed can be realized, the advance and retreat operation in real time synchronous can be realized simultaneously with roller-way.This device has utilized magnetic induction near switch, finishes that magnechuck lifts automatically, fast return and self-braking function, in the process of force feed steel plate, can realize that electromagnet goes up a whole set of control actions such as magnetic, degaussing automatically.
